HARRY DIFLO, 0F PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE ECLIPSEMETALLIC SPECIALTY COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A COR-PORATION 0F DELAWARE.

SAD-IRON.

To all fui/wm t may concern Be it known that I, HARRY DirLo, of the cityand county of Philadelphia and State of Pennsylvania, have inventedcertain new and useful yImprovements in Sad-Irons, of which thefollowing is a specification, reference being had to the accompanyingdrawings.

My invention relates to a sad iron, the hollow interior of which isprovided with a special combustion chamber, the thick metal walls ofwhich hold the heat, at the same time giving weight to the iron. Meansare provided for supplying gas and air to the combustion chamber, andthe walls of the combustion chamber are so shaped as to deflect flamepreventing the products of combustion from carrying the flame outthrough the side walls of the sad iron. In this way a maximum heating'effect is secured from a minimum amount of gas.

Other novel features are the three-piece casing, the false top and thelatched top, all of which will be hereinafter described.

A sad iron embodying my invention is illustrated in the accompanyingdrawings, in which- Figure I, is a plan View of the sad iron. Fig. II,is a side elevation of the same. Fig. III, is a central longitudinalsection of the same. Fig. IV, is a horizontal section, along the lineIV, IV, of Fig. III. Fig. V, is a vertical cross section along the lineV, V, of Fig. IV. Fig. VI, is a detail view of the catch for holding thehinged top in place.

The casing of the sad iron is formed of three pie( s each stamped fromsheet metal. 'lhese pie( consist. respectively of the base l, the wallpiece 2, and the top 3. The base l, is formed with an up iardlyprojecting peripheral flange, and the top 3, is formed with a similardownwardly projecting flange. rIhe wall piece is received within thevflanges of the base and top and fills the space between them. The wallpiece is se curely and permanently attached to the flanged base. rlhetop is not thus secured, but is hinged at the rear to the wall piece bymeans of projecting lugs il, 4t, engaging slots in the upper edge ofthis part of the wall piece.

To the top is secured, a handle, consisting of the wooden hand piece 5,and two bracket arms G, G, fastened to the handle, and alsoSpecification of Letters Patent.

(preferably by the screws 7, 7,), to the longitudinal center of the sadiron.

In order to hold the hinged top in place upon the iron, I provide alocking tongue 10, which is made fast to the wall piece near the forwardend of the sad iron, and which projects up through a correspondingaperture in the top piece near its nose. This locking tongue is providedwith a slot 11, which receives a latch piece l2, forwardly pressed intoengagement with it by the spring 13. This latch is a sliding' piece,preferably shaped as shown in Fig. VI so as to surround the attachmentof the forward bracket arm of the handle, which operates to guide thelatch piece. It is also provided with a thumb piece 14, for withdrawingthe latch when it is desired to open the sad iron.

'Io lessen the radiation. of heat through the top of the sad iron, Iprovide a false top 15, which is attached to the lower surface of thetop proper, with interposition of asbestos or similar non-combustiblepacking.

In order to permit observation of the liaine without opening the top, awindow 1S, is provided in the rear wall of the sad iron, protected by atransparent piece of isinglass lf), and held in place by the metal piece17.

`Within the hollow interior of the sad iron is inserted the heavy metalconduction piece 20, which is provided with a central combustion chamber2l, having upwardly flan ing or inclined walls lhis conduction piece hasa three-fold purposez--to forni the cinnbustion chamber, to conduct theheat to the base plate and to give weight to the sad iron. lVithin thecombustion chamber formed in the interior of this conduction piece a gassupply pipe 23, is inserted, occupying about the central part of saidchainber. This pipe is supported forwardly by the supporting lug- 2.5.and rearwardly by the rear wall of the Sad iron.

The gas supply pipe is perforated by jet apertures 29. The combustionchamber has air supply passages 30, 30, consisting of channels formed inthe comluction piece, and registering with corresjionding openingsforined in the walls of the sad iron. These supply air to the combustionchamber, so that the gas from the gas pipe is burned therein in the formof jets.

An important feature of my invention consists in placing the gas Isupplypipe with in the combustion chamber, well below its upper edge. Therebythere is provided a large inetal heat absorbing surface almostsurrounding the combustion chamber, and thereby also the direct passageis prevented of flame from the combustion chamber to the exit holes 4.0,with which the wall piece of the sad iron is provided near its top.

The projection of the flanges of the top and bottom piece on the outersurface of the wall piece serves to protect the apertures of the wallpiece from being teniporarily choked by "contact with the goods whichare being ironed.

Having thus described iny invention, 1 claim:

1. A sad iron provided with a casing containing a vheavy metalconduction piece, which is provided with a central combustion chamber,open at the top and ruiming from the front to the rear of the conductionpiece, said chamber having upwardly flaring walls, a gas supply pipewithin the combustion chamber7 and air supply apertures piercing thewalls of the conduction piece, and leading t0 the combustion chamber.

9,. A- sad iron provided with -a casing, which is orn'ied oi a baseplate with an upwardly projecting peripheral lia-nge, a top plate with adownwardly projecting peripheral flange7 and a wall piece receivedwithin said fianges and occupying the space between the two, a heavymetal conducting ,piece7 located within said casing' and engaging theinner face of said wall piece, said conduction piece being provided witha central combustion chamber, open at the top and running from the frontto the rear of the conduction piece, a gas supply pipe within thecombustion chamber, and air supply apertures piercing the wall piece,and the walls of the conduction piece, and leading t0 the combustionchamber.

In testimony whereof, 1 have hereunto signed my naine, at Philadelphia,Pennsylvania, this fourth day of August, 1911.
